Gross Income Breakdown
The starting point of our calculation is the gross salary. For this example, I’m assuming an annual salary of $100,000. However, this figure is only the starting point. To calculate the net pay, we must account for various deductions, including taxes, Social Security, Medicare, and state income tax.
Federal Income Tax
The federal tax system in the United States is progressive, meaning that the more you earn, the higher percentage of your income you pay in taxes. The IRS uses tax brackets to determine how much of your income is taxed at each rate.
For the year 2025, the federal tax brackets for a single filer are as follows:
- 10% on income up to $11,000
- 12% on income from $11,001 to $44,725
- 22% on income from $44,726 to $95,375
- 24% on income from $95,376 to $182,100
- 32% on income from $182,101 to $231,250
- 35% on income from $231,251 to $578,100
- 37% on income above $578,100
For a salary of $100,000, the taxable income will be reduced by the standard deduction. For 2025, the standard deduction for a single filer is $13,850. This means that your taxable income will be:
100,000 - 13,850 = 86,150 , \text{USD}Next, we apply the tax brackets to this taxable income:
- The first $11,000 is taxed at 10%:
The income between $11,001 and $44,725 (i.e., $33,725) is taxed at 12%:
33,725 \times 0.12 = 4,047 , \text{USD}The income between $44,726 and $86,150 (i.e., $41,425) is taxed at 22%:
41,425 \times 0.22 = 9,113.50 , \text{USD}The total federal tax owed will be the sum of these amounts:
1,100 + 4,047 + 9,113.50 = 14,260.50 , \text{USD}New Jersey State Income Tax
In addition to federal taxes, New Jersey imposes its own state income tax, which is also progressive. The state income tax brackets for a single filer in New Jersey for 2025 are as follows:
- 1.4% on income up to $20,000
- 1.75% on income from $20,001 to $35,000
- 3.5% on income from $35,001 to $40,000
- 5.525% on income from $40,001 to $75,000
- 6.37% on income from $75,001 to $500,000
For our example, the taxable income for New Jersey state tax is the same as the taxable income for federal tax: $86,150.
Let’s break it down by tax brackets:
- The first $20,000 is taxed at 1.4%:
The income between $20,001 and $35,000 (i.e., $15,000) is taxed at 1.75%:
15,000 \times 0.0175 = 262.50 , \text{USD}The income between $35,001 and $40,000 (i.e., $5,000) is taxed at 3.5%:
5,000 \times 0.035 = 175 , \text{USD}The income between $40,001 and $75,000 (i.e., $35,000) is taxed at 5.525%:
35,000 \times 0.05525 = 1,933.75 , \text{USD}The income between $75,001 and $86,150 (i.e., $11,150) is taxed at 6.37%:
11,150 \times 0.0637 = 711.36 , \text{USD}The total state income tax owed will be:
280 + 262.50 + 175 + 1,933.75 + 711.36 = 3,362.61 , \text{USD}Social Security and Medicare Taxes
In addition to federal and state income taxes, employees must also pay Social Security and Medicare taxes. These are fixed percentages of your income and are not affected by tax brackets.
- Social Security: 6.2% on income up to $160,200 (as of 2025)
- Medicare: 1.45% on all income (no cap)
For a $100,000 salary, here’s how these taxes break down:
- Social Security tax:
Medicare tax:
100,000 \times 0.0145 = 1,450 , \text{USD}So, the total Social Security and Medicare taxes would be:
6,200 + 1,450 = 7,650 , \text{USD}Total Tax Deductions
Now that we have calculated the federal income tax, state income tax, and Social Security and Medicare taxes, let’s total up the deductions:
- Federal income tax: $14,260.50
- New Jersey state income tax: $3,362.61
- Social Security tax: $6,200
- Medicare tax: $1,450
The total tax deductions are:
14,260.50 + 3,362.61 + 6,200 + 1,450 = 25,273.11 , \text{USD}Net Pay After Taxes
To calculate the net pay, we subtract the total tax deductions from the gross income of $100,000:
100,000 - 25,273.11 = 74,726.89 , \text{USD}Therefore, after all federal, state, and payroll taxes, your take-home pay from a $100,000 salary in New Jersey will be approximately $74,726.89.
